1Fertilization strategy and application model using a centrifugal variable-rate fertilizer spreader显示文摘With the sustainable development of precision agriculture and the steady progress of variable-rate fertilization technology,the centrifugal variable-rate fertilizer spreader has attracted research attention due to its lower incidence of crush damage,high efficiency,and low cost.To improve fertilization accuracy and uniformity,spreading performance tests were conducted using this spreader in accordance with the test methods specified in ISO 5690 and ASAE S341.2,in which particle mass was weighed in a two-dimensional matrix of collection boxes.The effects of fertilization strategies that control the feed gate flow rate and the disc rotation speed on particle distribution,and application rate per unit area and effective swath width,were investigated.A variable-rate fertilization model was developed by analyzing the variation characteristics resulting from an increasing and decreasing application rate,and field experiments were conducted to verify its accuracy.The results indicated that when the feed gate flow rate was 300 g/s,the mean application rate was 26.47 g,the standard deviation is 2.81,and the coefficient of variation of particle distribution is at its minimum value of 14.25%.When the disc rotation speed was 600 r/min,the fertilizer was most evenly distributed with a coefficient of variation of 13.86%,and an average effective spreader swath width of 24.51 m.The proposed variable-rate fertilization model showed a high fitting degree with an S-shaped function curve for both increasing and decreasing distribution rates and the yielding coefficients of determination were more than 0.82 and 0.71,respectively.The average error between the model predictions and the test results was 9.47%,and the coefficients of determination for the increasing and decreasing distribution rates were 0.91 and 0.82,respectively,which confirmed the accuracy of the proposed variable-rate fertilization model.This investigation provided a theoretical basis for traditional empirical fertilization using centrifugal variable-rate fertilizer spreaders,and guides the selection of a multiple trajectory,variable-rate fertilization strategy.Yinyan Shi Zhichao Hu Xiaochan Wang Morice O.Odhiambo Guoxiang Sun 2018International Journal of Agricultural and Biological Engineering2018,11,6:6

4Types of community health services selected by urban and suburban residents in Nanjing and influencing factors显示文摘Objective:The purpose of the current study was to determine the types of community health services selected by urban and suburban residents in Nanjing and the influencing factors in an ef-fort to improve the community health services to better meet the residents’demands.Methods:Between 15 May 2013 and 15 June 2013,eight community health service centers from four districts in Nanjing(Gulou District and Baixia District in urban areas and Jiangning District and Pukou District in suburban areas;two centers from each district)were selected using a stratified random sampling method of investigation sites.After an intercept interview with 487 community residents,univariate and multivariate analyses were performed by means of logistic regression.Results:Among the 487 users of community health services,there were 241 residents from urban areas(49.5%)and 246 residents from suburban areas(50.5%).Among the respondents,there were 191(39.2%)who usually received medical treatment from community health service institutions,including 74(38.7%)from urban areas and 117(61.3%)from suburban areas.The analysis showed that the factors which influenced urban residents in Nanjing to choose community health services for medical treatment included income,payment terms of medical fees,reasonable prices,medical fees,and expenses for medications,while factors influencing suburban residents to choose community health services for medical treatment included income,level of education,carrier,medical institutions selected when feeling severely ill,availability of preventive health services,availability of health counseling services,medical fees,and expenses for medications.Based on an analysis of the results by means of unconditioned binary logistic stepwise regression,the factors influencing whether or not the urban residents chose community health services for medical treatment included gender,age,level of education,payment terms of medical fees,treat-ment environment,and expenses for medications,while the factors influencing suburban residents included availability of preventive health services and expenses for medications.Conclusion:There was a difference between the types of community health services selected by residents in urban and suburban areas of Nanjing and factors influencing the selection of ser-vices were different.Community health service institutions in different areas should strengthen their own service capability according to the local residents’health demands.Hong Fan Qianyuan Wang Yinyan Wu 2014Family Medicine and Community Health2014,2,1:4
5Classification of brain arteriovenous malformations located in motor-related areas based on location and anterior choroidal artery feeding显示文摘Objective Surgical management of arteriovenous malformations(AVMs)involving motor cortex or fibre tracts(M-AVMs)is challenging.This study aimed to construct a classification system based on nidus locations and anterior choroidal artery(AChA)feeding to pre-surgically evaluate motor-related and seizure-related outcomes in patients undergoing resection of M-AVMs.Methods and materials A total of 125 patients who underwent microsurgical resection of M-AVMs were retrospectively reviewed.Four subtypes were identified based on nidus location:(I)nidus involving the premotor area and/or supplementary motor areas;(II)nidus involving the precentral gyrus;(III)nidus involving the corticospinal tract(CST)and superior to the posterior limb of the internal capsule;(IV)nidus involving the CST at or inferior to the level of posterior limb of the internal capsule.In addition,we divided type IV into type IVa and type IVb according to the AChA feeding.Surgical-related motor deficit(MD)evaluations were performed 1 week(short-term)and 6 months(long-term)after surgery.Results The type I patients exhibited the highest incidence(62.0%)of pre-surgical epilepsy among the four subtypes.Multivariate analysis showed that motor-related area subtypes(p=0.004)and diffuse nidus(p=0.014)were significantly associated with long-term MDs.Long-term MDs were significantly less frequent in type I than in the other types.Type IV patients acquired the highest proportion(four patients,25.0%)of long-term poor outcomes(mRS>2).Type IVb patients showed a significantly higher incidence of post-surgical MDs than type IVa patients(p=0.041).The MDs of type III or IV patients required more recovery time.Of the 62 patients who had pre-surgical seizures,90.3%(56/62)controlled their seizures well and reached Engel class I after surgery.Conclusions Combining the consideration of location and AChA feeding,the classification for M-AVMs is a useful approach for predicting post-surgical motor function and decision-making.Yuming Jiao Hao Li Weilun Fu Jiancong Weng Ran Huo Yinyan Wang Shuo Wang Tao Jiang Yong Cao Ji Zong Zhao 2021Stroke & Vascular Neurology2021,6,3:4

11Response characteristics and efficiency of variable rate fertilization based on spectral reflectance显示文摘The key technical problem of variable rate fertilization system based on spectrum information was precise variable fertilization in certain area according to the acquired spectrum information.Hysteretic fertilizing is a critical problem in most of current fertilizer equipment.Hysteresis model was built and analyzed in this study to improve the system.Fertilizing tests were conducted on different wheat breeds and the results were analyzed.The tests showed that variable rate fertilization had obvious hysteresis phenomenon with the maximum lag distance of 3.82 m,the minimum lag distance of 1.73 m and average of 3.06 m.Hysteresis phenomenon of the variable rate fertilization system was obviously decreased when implanting a correction time of 2.04 s with the maximum lag distance of 0.61 m.Variable effects varied by different wheat breeds.Variable rate fertilization had an advantage of improving spatial differences of Yangmai-23,and the spatial variability of which decreased by 14.23%.In the small test area,the amount of fertilizer in Zhenmai-168 decreased by 2.84 kg,while the amount of which in Yangmai-23 increased by 3.83 kg.Yield of Zhenmai-168 in small area was lower than that in traditional pattern,but the condition of Yangmai-23 was on the contrary.Valuable information for increasing performance of fertilization in variable rate fertilization system was provided in this paper.Man Chen Zhenjie Yang Xiaochan Wang Yinyan Shi Yu Zhang 2018International Journal of Agricultural and Biological Engineering2018,11,6:1

18Molecular Study on Differentiation-Associated Genes Involved in Both Malignant Progression of Glioma and Differentiation of Human Fetal Neural Stem Cells显示文摘OBJECTIVE It is unclear whether differentiation disturbances or deregulation of neural stem cells (NSCs) are the early key steps for gliomagenesis and tumor development. Furthermore, relevant molecular changes and gene-regulation pathways are unknown. This study focused on screening and validating differentiation-associated genes from both human NSCs and glioma cells with malignant progression, for the purpose of offering an experimental basis for the cellular origin of gilomas and molecular pathology of gliomagenesis. METHODS The differential-gene expression profiles of malignant progression of gliomas were established, then the differentiation related genes were screened out with a bioinformatics analysis. Expression levels of these genes was further analyzed in cultured human fetal NSCs undergoing differentiation processes with a semi-quantitative RT-PCR assay. RESULTS Eight genes were screened out from the gene-expression profiling of which the expression levels were associated with the differentiation processes of NSCs, namely CXCR4, TN-C, GLT1, IL1-RI, EGFR-8, CDC2, Ndr3 and MAPKK4. Three of them, ie., GLT1, CDC2 and MAPKK4, were further analyzed, showing that expression levels decreased with the differentiation processes of NSCs, and increased with the malignant progression of ganglioglioma. CONCLUSION Three differentiation associated genes were found negatively associated with NSCs differentiation and positively associated with malignant progression of gliomas, suggesting that differentiation disturbances of neural stem cells may be involved in oncogenesis, and that further studies on their roles in gliomagenesis should be conducted.Jun Dong Yinyan Wu Qiang Huang Fei Wang Aidong Wong Qing Lan 2006Chinese Journal of Clinical Oncology2006,3,6:1
19Quantum discord in the three-spin XXZ chain with Dzyaloshinskii-Moriya interaction显示文摘The quantum discord(QD) of a three-qubit Heisenberg XXZ system with the Dzyaloshinskii-Moriya(DM) interaction parameter is investigated,and the three-qubit QD under Ornstein-Uhlenbeck noise is calculated.We find that both DM interaction parameter D z and anisotropic parameter J z can increase QD and entanglement but D z is a more efficient parameter in the antiferromagnetic case.We observe a complex range of QD with the change of D z and a sudden change of QD with the variation of J z in the ferromagnetic case.We show that the decrease durations of both QD and entanglement can be prolonged by increasing DM interaction and reducing noise bandwidth in the evolutionary process.ZHU YinYan ZHANG Yong 2012Science China(Physics,Mechanics & Astronomy)2012,55,11:1
